Automobile Pollution Essay Example for Free

Automobile Pollution EssayExponential growth in petrol and diesel fueled vehicles are responsible for deterioration of air quality in cities. Beca social function of the increase in urbanization, industrialization and commercial activities in the urban areas, the demand for transport has also been increased. In addition to it the use of personal vehicles has also increase steadily. The various principle pollutants hap from vehicles are as follows- Carbon monoxide (CO) hang up particulate matter (SPM) Oxides of nitrogen (NOx) Hydrocarbons (HC) Polynuclear aromatic hydrocarbons (PAHs).2005 Air Toxic Emissions from On-road Mobile Sources (Tox-weighted) Affects of Automobile Pollution 1. In India about 15-20 million people are asthmatic because of sacking of automobile pollution. 2. N02 is a highly toxic gas and attacks the lungs causing lung cancer and emphysema. 3. Automobile pollutants interferes the development and functioning of the nervous corpse. 4. Some diseases such as bronchitis, plurosis occur by long-term exposure to the particulate matter. 5. N02 reacts with hydrocarbons and creates photochemical smog.Reasons for Automobile Pollution The petrol goaded vehicles emit invisible gases such as CO and Benzene while diesel driven vehicles emit mainly black smog containing minute carbon particles and S02. The main reasons for vehicular pollution problems are as follows- 1. Poor quality of fuel 2. Outdated vehicles 3. Congestion and mixed traffic of different types 4. Lack of puritanical traffic management Important Pre-requisites for Controlling Vehicular Pollution 1. Phasing out of grossly polluted vehicles 2. Enforcement of expelling norms for new and in-use vehicles.3. Improvement in automobile technology 4. Reduction of lead content in drive fuel 5. Stream lining traffic management 6. Improvement in public transport system 7. Fuel quality improvement and switch everywhere to cleaner fuel 8. Restriction on undiscriminating growth of urban cent ers, industrial and commercial activities Alternative Fuels Hydrogen Gas It can be utilize in modified combustion engines and is eco-friendly as it emits water vapours only. Electric Vehicles They are advantageous over conventional fueled vehicles as far as environment is concerned.Ethanol It can be utilise in regular automobiles after blending with petrol. It is rather clean fuel with low nitrogen oxide and hydrocarbons emission and no net C02 emission. Methanol It is a liquid fuel and is produce from coal, natural gas and biomass. ft emits very little NOx and HC. Natural gas It exists in the gaseous state at radiation diagram temperature and pressure and is found in the form of CNG and LPG. It causes substantially lower pollution without affecting the performance of the vehicles.
